    So I KNOW this subject has been beaten to death...battery life...however, I have some things I am doing and I don't know if I have too much going on and I need to remove some apps or if my battery is messed.

    *I got the extended battery on Tuesday
    *rooted my DX with z4root, installed titanium backup and froze a bunch of worthless apps.
    *downloaded Juice Defender Ultimate and changed my CPU to min 300, max idle 300 and max 800
    *Juice defender also has all data disabled.
    *Juice defender icon says x1.69 (don't know what that means)
    *my 3G is disabled by Quick settings almost ALL the time and I don't have Wifi accesss
    *I have my screen set to timeout at 15 secs and using the lowest amount of light possible
    *GPS turned off
    *Social networking turned off
    *email and weather apps turned off
    *No antivirus or task killers
    *I have Android Assistant downloaded but it seems to be running all the time (and it does have a task killer and a pie chart telling me my CPU at all time...actually scratch it, Uninstalling as we speak)
    *Under settings, I have my Data Manager background data, data roaming and data enabled all turned off
    *I have my CDMA turned to Home settings (rather than Automatic) and CDMA auto prl (in that special code you dial and get the secret menu)
    *Airplane mode at night while I am sleeping
    *once my battery is charged to 100% I plan on Going to data>system>and delete batterystats.bin

    SOOO....based on that information, the battery was last fully charged Wednesday morning at 5:30 am. and went all day on Wednesday down to 50% battery at bedtime and when I woke up this morning, it was 30% with airplane mode on! As I type it is 20%. So all day today it went from 30%-20% but that is texting maybe 5 times and talking one time for 5 mins. The phone has been idle most of the day. In my mind, I still don't know where all my power is going. It seems like with such minimal usage, the battery should stay charged longer considering I have everything turned off all day. I am not even using the phone the way it should be used and I have the extended battery.

    Can someone tell me what program I should remove, what's sucking my battery life, what I am doing wrong? The extended battery has only been charged one time since I bought it and I am thinking maybe it needs some training. I am going to let it die completely tonight then charge it (should it stay off or turn back on during charging?). I am just worried that I need a bigger battery or that I have something running in the background that I don't know about.

    I just want to know what else I can do, if anything to conserve more battery, esp. if I decide to actually start using the phone to do what the phone is meant to do!

    here is what is using the battery:

    Phone idle 24%
    Cell Standby 19%
    android system 17%
    Display 14%
    android OS 7%
    Motorola services 7%
    com.motorola.hom 4%
    boot animation 3%
    com.motorola.providers.something 3%
    com.android.phone 2%

    Advice please...do I have a bum battery?

    My understanding is airplane mode turns off ALL radios so you can't get a call either. You might as well just turn it off.

    I had better battery life with Battery Saver mode than with Juice.

    You can delete battery stats with recovery (under advanced).

    Do you have a recovery backup you can load if you screwed up something freezing all those worthless apps? Sometimes uninstalling or freezing things can make battery life worse. That's why I recommend just backing up stock and installing a rom, if you want to get rid of bloat.

    FWIW, I didn't see anything in your battery use that said what the problem was but 3% boot animation doesn't sound right. Did you reboot your phone 50 times?

    A new battery takes 2 to 3 full charge/discharge cycles to get optimal capacity.

    I use mine all day long with the extended battery. on an average day I get about 200 emails pushed, 5 to 10 text messages, about 30 minutes total of calls, reading news about an hour. at the end of the day I usually have 50 to 60% left.

    In airplane mode (tested while on vacation in a foreign country that does not have cdma coverage) I was able to get over 2 weeks of use on one charge. which included some short email via wifi couple times a day.

    Overall the X has excellent battery life!

    yes, I did do a couple reboots b/c I was trying to figure out what was screwed up with my text messages and so i kept having to do a soft reboot after I got my phone's roaming settings activated, the i installed z4root, and titanium backup then i did bootstrap recovery. however this morning, my stats are a little different

    Juice defender is x2.29 which is good
    battery is being drained by
    display 38%
    Phone idle 27%
    cell standby 22%
    android system 7%
    com.motorola.home 2%
    text message 2%

    that's it on my battery stats screen

    so you are saying freezing apps like skype mobile, blockbuster or madden football can make my battery life worse...can you explain why?

    also, is battery saver an app (does it have another name is goes by like screebl or is actually called battery saver) or are you talking about battery mode on the settings menu where I can customize my battery saving mode? Just want to be clear on what I need to do. The only reason I use juice defender is so I can change my CPU settings. I have them set at min 300, max idle 300 and max 800. Juice defender ulitmate gave me that option where as the battery saving mode on the phone did not.

    What extended battery brand is it? How many MaH?

    +1... takes days for a phone to understand the capabilities of any new battery. You should charge it up and run it nearly dead the first time, and it will do nothing but improve after that.

    I use QuickClock (there is a free version) and Overclock to overclock and undervolt my X. Can't say it makes a huge difference in battery life, but I like to tweak and tune. My day job is IT, if that says anything. I OC to 1,250 with a little higher voltage than QC recommends for stability. I've overclocked computers for years until I was into laptops, which are harder to tune.

    When I referenced freezing apps, I was speaking in generalities, not skype, BB, Madden, in particular, but stick by my rom-is-easier-than-freezin'-stuff comment. Apex is known for good battery life.

    Maximum Battery Saver is a setting under your phone' Battery Manager settings.

    If you think you have something using your battery in an inappropriate way, I like Watchdog to monitor that. You only need to run it for a few days IMO. Once I had an app that used a lot of cpu, but after I rebooted, all was good.

    Going against what most people say, it's actually bad for the battery to drain it all the way down. Lithium ion batteries don't need to be "trained." It's better for the battery to receive many partial charges, rather then full discharges. If you do fully drain the battery, I would only do so after ~30 charges. I have the extended battery, but run custom ROMs, maybe try a ROM out, they seem to have much better battery life across the board.

    Correct.

    When you swap out a battery in a new phone, you're not training the battery. You're letting the phone learn the capabilities of the phone. The only way to do that is to discharge it.

    Correct. The purpose of draining the battery isn't to train the battery, but rather to allow the phone the opportunity to properly read the capacity of the battery.

    It is not bad for a lithium battery to be drained.

    It is bad for a lithium battery to be discharged past a safe voltage, but every lithium powered consumer device has a shutdown mechanism in place to prevent a deep discharge of the lithium battery.

    Now, it's not great practice to repeatedly fully discharge and recharge a lithium battery as the standard mechanism of use, but it's not bad for the battery to be drained all the way.

    Bad info

    Good info.

    Yes, it is not good for Litium Ions to be completely drained, that why as Binary Visions correctly stated that they have protection circuitry on them to ensure that can't happen.

    The thing that degrades the batteries lifetime, however, is charging cycles. That is why as k0smo86 incorrectly stated that many small charging cycles is more more beneficial is completely false. The more times you charge a Lithium Ion cell, the less it will last. Best use is to only charge when the phone tells you to. That will provide the longest battery life as well as highest charge capacity.
